Taking to Instagram, the player wrote: "Hi Everyone-I want to reach out and let my fans and friends know that I tested positive back in Monaco for Covid-19. I want to make sure anyone who has been in contact with me during these past days gets tested and takes the necessary precautions. I am so sorry for any harm I might have caused. I am back home now and recovering. Thanks for your support and please stay safe and healthy."
After testing COVID-19 positive, Grigor has also urged all players and staff who had come in contact with him over the last few days in Monaco should also get tested for the deadly virus.
Meanwhile, World no.1 Djokovic reached the final of his exhibition tournament in Zadar, Croatia, after brushing aside opponents in the round-robin group stage on the first day. This is the second stage of the Adria Tour with Austrian Dominic Thiem winning the first leg in Belgrade, Serbia.
Djokovic started by saving three set points in his 4-3, 4-1 win over fellow Serb Pedja Krstin. He then beat home favourite Borna Coric 4-1, 4-3 in front of several thousand fans at the Visnjik tennis complex.
The tournament in Zadar is being played on red clay over two days. In the other group, Russian Andrey Rublev is in pole position to advance into the final after wins over 2014 US Open champion Marin Cilic and Serb Danilo Petrovic. He faces German star Alexander Zverev in the final round robin match on Sunday who stayed in contention after beating Cilic 4-3, 0-4, 4-3.
Djokovic's own inconsequential final group match is against Croatian Dino Serdarusic who replaced Grigor Dimitrov after the Bulgarian pulled out of the tournament with sickness following his opening 4-1, 4-1 loss to Coric.
